Mapping Transmission Dynamics and Drug Resistance Surveillance in the Cyprus HIV-1 Epidemic (2017-2021).

The human immunodeficiency virus type 1 (HIV-1) epidemic has been a major public health threat on a global scale since the early 1980s. Despite the introduction of combination antiretroviral therapy (cART), the incidence of new HIV-1 infections continues to rise in some regions around the world. Thus, with the continuous transmission of HIV-1 and the lack of a cure, it is imperative for molecular epidemiological studies to be performed, to monitor the infection and ultimately be able to control the spread of this virus. This work provides a comprehensive molecular epidemiological analysis of the HIV-1 infection in Cyprus, through examining 305 HIV-1 sequences collected between 9 March 2017 and 14 October 2021. Employing advanced statistical and bioinformatic techniques, the research delved deeply into understanding the transmission dynamics of the HIV-1 epidemic in Cyprus, as well as the monitoring of HIV-1's genetic diversity and the surveillance of transmitted drug resistance. The characterization of Cyprus's HIV-1 epidemic revealed a diverse landscape, comprising 21 HIV-1 group M pure subtypes and circulating recombinant forms (CRFs), alongside numerous uncharacterized recombinant strains. Subtypes A1 and B emerged as the most prevalent strains, followed by CRF02_AG. The findings of this study also revealed high levels of transmitted drug resistance (TDR) patterns, raising concerns for the efficacy of cART. The demographic profiles of individuals involved in HIV-1 transmission underscored the disproportionate burden borne by young to middle-aged Cypriot males, particularly those in the MSM community, who reported contracting the virus in Cyprus. An assessment of the spatiotemporal evolutionary dynamics illustrated the global interconnectedness of HIV-1 transmission networks, implicating five continents in the dissemination of strains within Cyprus: Europe, Africa, Asia, North America, and Oceania. Overall, this study advances the comprehension of the HIV-1 epidemic in Cyprus and highlights the importance of understanding HIV-1's transmission dynamics through continuous surveillance efforts. Furthermore, this work emphasizes the critical role of state-of-the-art bioinformatics analyses in addressing the challenges posed by HIV-1 transmission globally, laying the groundwork for public health interventions aimed at curbing its spread and improving patient outcomes.

Small populations of Palaeolithic humans in Cyprus hunted endemic megafauna to extinction.

The hypothesized main drivers of megafauna extinctions in the late Quaternary have wavered between over-exploitation by humans and environmental change, with recent investigations demonstrating more nuanced synergies between these drivers depending on taxon, spatial scale, and region. However, most studies still rely on comparing archaeologically based chronologies of timing of initial human arrival into naïve ecosystems and palaeontologically inferred dates of megafauna extinctions. Conclusions arising from comparing chronologies also depend on the reliability of dated evidence, dating uncertainties, and correcting for the low probability of preservation (Signor-Lipps effect). While some models have been developed to test the susceptibility of megafauna to theoretical offtake rates, none has explicitly linked human energetic needs, prey choice, and hunting efficiency to examine the plausibility of human-driven extinctions. Using the island of Cyprus in the terminal Pleistocene as an ideal test case because of its late human settlement (~14.2-13.2 ka), small area (~11 000 km2), and low megafauna diversity (2 species), we developed stochastic models of megafauna population dynamics, with offtake dictated by human energetic requirements, prey choice, and hunting-efficiency functions to test whether the human population at the end of the Pleistocene could have caused the extinction of dwarf hippopotamus (Phanourios minor) and dwarf elephants (Palaeoloxodon cypriotes). Our models reveal not only that the estimated human population sizes (n = 3000-7000) in Late Pleistocene Cyprus could have easily driven both species to extinction within < 1000 years, the model predictions match the observed, Signor-Lipps-corrected chronological sequence of megafauna extinctions inferred from the palaeontological record (P. minor at ~12-11.1 ka, followed by P. cypriotes at ~10.3-9.1 ka).

Food insecurity and its association with socio-demographic characteristics in Cyprus.

The prevalence of food insecurity in Cyprus and the socio-demographic factors that are related to this public health problem are unknown. Data used in this cross-sectional study were collected between 1 June 2022 and 21 May 2023 using a self-reported method. Food insecurity was evaluated using the Greek version of Adult Food Security Survey Module. The data regarding socio-demographic and socio-economic characteristics along with body weight and height measurements were collected through self-administered questionnaire. A representative sample of n=1255 adults, ≥18 years old living in the five different districts of the Republic of Cyprus, was recruited. Prevalence of food insecurity in Cypriot population was 12.6%. Prevalence was higher in females, in older adults, in adults living in Paphos, in individuals who were separated, divorced, or widowed, in retired people, in people living with children, and in people with low income and education. Based on multivariable analysis, income was the strongest socio-demographic factor independently associated with food security (€ 6,500-€ 19,500: AOR: 0.49, 95% CI 0.28, 0.86 and >€ 19,500: AOR: 0.15, 95% CI 0.73, 0.31). Food insecurity is a global problem that need further examination. The association between food insecurity and socio-demographic characteristics needs to be highlighted in order for each country to develop specific public health policies (e.g. financial support to low income people) to decrease food insecurity and improve people's overall health and quality of life.

Gender-Specific Variations in Greater Palatine Foramen Anatomy: Insights from CBCT Scans in the North Cyprus Population.

BACKGROUND The greater palatine foramen (GPF) is anatomically located distal to the third maxillary molar tooth, midway between the midline of the palate and the dental arch. The GPF contains the major palatine artery, vein, and nerve, traversing the palatine sulcus. This study aimed to evaluate the anatomical position of the GPF in 93 women and 67 men at a single center in Cyprus using cone beam computed tomography (CBCT). MATERIAL AND METHODS A retrospective analysis was conducted on 160 CBCT scans. Measurements of the GPF's horizontal and vertical diameters, distances from GPF to the incisive foramen, posterior nasal spine, anterior nasal spine, and midaxillary suture, and positional relationships to molars were recorded. Statistical analyses compared these measurements between males and females. RESULTS The study included 93 females and 67 males with an average age of 46.6 (±11.6) years. Significant sex differences were observed in most GPF measurements, with males showing larger dimensions such as the anterior nasal spine, posterior nasal spine, mid-maxillary suture, and incisive foramen to the GPF. The GPF was predominantly located in the third molar region (96.25% on the right, 96.9% on the left). The left GPF showed a significantly larger horizontal diameter than the right (P<0.05). CONCLUSIONS There was a significant difference in the average distances from the anterior nasal spine, posterior nasal spine, mid-maxillary suture, and incisive foramen to the GPF, as well as in the size of the GPF, between males and females. Recognizing these variations enhances clinical planning and reduces the risk of complications.

Dynamical analysis of methicillin-resistant Staphylococcus aureus infection in North Cyprus with optimal control: prevalence and awareness.

The number of Methicillin-resistant Staphylococcus aureus (MRSA) cases in communities and hospitals is on the rise worldwide. In this work, a nonlinear deterministic model for the dynamics of MRSA infection in society was developed to visualize the significance of awareness in interventions that could be applied in the prevention of transmission with and without optimal control. Positivity and uniqueness were verified for the proposed corruption model to identify the level of resolution of infection factors in society. Furthermore, how various parameters affect the reproductive number R 0 and sensitivity analysis of the proposed model was explored through mathematical techniques and figures. The global stability of model equilibria analysis was established by using Lyapunov functions with the first derivative test. A total of seven years of data gathered from a private hospital consisting of inpatients and outpatients of MRSA were used in this model for numerical simulations and for observing the dynamics of infection by using a non-standard finite difference (NSFD) scheme. When optimal control was applied as a second model, it was determined that increasing awareness of hand hygiene and wearing a mask were the key controlling measures to prevent the spread of community-acquired MRSA (CA-MRSA) and hospital-acquired MRSA (HA-MRSA). Lastly, it was concluded that both CA-MRSA and HA-MRSA cases are on the rise in the community, and increasing awareness concerning transmission is extremely significant in preventing further spread.

Projections of mortality attributable to hot ambient temperatures in Cyprus under moderate and extreme climate change scenarios.

BACKGROUND: Heat-related mortality has become a growing public health concern in light of climate change. However, few studies have quantified the climate-attributable health burden in Cyprus, a recognized climate change hotspot. This study aims to estimate the heat-related mortality in Cyprus for all future decades in the 21st century under moderate (SSP2-4.5) and extreme (SSP5-8.5) climate scenarios. METHODS: We applied distributed lag non-linear models to estimate the baseline associations between temperature and mortality from 2004 to 2019 (data obtained from Department of Meteorology of the Ministry of Agriculture, Rural Development and Environment and the Health Monitoring Unit of the Cyprus Ministry of Health). The relationships were then extrapolated to future daily mean temperatures derived from downscaled global climate projections from General Circulation Models. Attributable number of deaths were calculated to determine the excess heat-related health burden compared to the baseline decade of 2000-2009 in the additive scale. The analysis process was repeated for all-cause, cardiovascular, and respiratory mortality and mortality among males, females, and adults younger or older than 65. We assumed a static population and demographic structure, no adaptation to hot temperatures over time, and did not evaluate potential interaction between temperature and humidity. RESULTS: Compared to 2000-2009, heat-related total mortality is projected to increase by 2.7% (95% empirical confidence interval: 0.6, 4.0) and 4.75% (2.2, 7.1) by the end of the century in the moderate and extreme climate scenarios, respectively. Cardiovascular disease is expected to be an important cause of heat-related death with projected increases of 3.4% (0.7, 5.1) and 6% (2.6, 9.0) by the end of the century. Reducing carbon emission to the moderate scenario can help avoid 75% of the predicted increase in all-cause heat-related mortality by the end of the century relative to the extreme scenario. CONCLUSIONS: Our findings suggest that climate change mitigation and sustainable adaptation strategies are crucial to reduce the anticipated heat-attributable health burden, particularly in Cyprus, where adaptation strategies such as air conditioning is nearing capacity.

Behavioral, cognitive and emotional determinants of getting vaccinated for COVID-19 and the mediating role of institutional trust among young adults in Cyprus.

BACKGROUND: Vaccination uptake is a complex behavior, influenced by numerous factors. Behavioral science theories are commonly used to explain the psychosocial determinants of an individual's health behavior. This study examined the behavioural, cognitive, and emotional determinants of COVID-19 vaccination intention based on well-established theoretical models: Acceptance and Commitment Therapy (ACT), Capability, Opportunity, Motivation, and Behaviour (COM-B) and the Health Belief Model (HBM). Additionally, it examined the mediating role of institutional trust in the relationship between determinants of these models and vaccination intentions. METHODS: A cross-sectional study was conducted from January to May 2022, where university students in Cyprus completed an online survey. RESULTS: A total of 484 university students completed the online survey, with 23.8% reporting being vaccinated with fewer than three vaccination doses and/or no intention to vaccinate further. Hierarchical logistic regression analysis showed that higher scores in institutional trust, perceived severity, motivation, physical and psychological capability were significantly associated with higher odds of intending to vaccinate. Higher psychological flexibility and not being infected with COVID-19 were also associated with higher odds of vaccination intention, but not in the final model when all determinants were included. Additionally, significant indirect effects of psychological and physical capability, motivation and perceived severity on vaccination intention were found to be mediated by institutional trust. CONCLUSIONS: When tackling COVID-19 vaccination hesitancy, behavioural, cognitive, and emotional aspects should be considered. Stakeholders and policymakers are advised to implement targeted vaccination programs in young people while at the same time building trust and improving their capabilities and motivation towards getting vaccinated.

Evaluation of Resilience and Mental Health in the "Post-Pandemic Era" among University Students: Protocol for a Mixed-Methods Study.

BACKGROUND: The mental well-being of university students has been a growing concern in Public Health and has been exacerbated by the COVID-19 pandemic. The pandemic (including the post-pandemic era) introduced and exacerbated a variety of potential stressors for vulnerable individuals and communities, resulting in an increase in mental health issues among university students. Resilience, as a process, is the ability of a system to adapt and grow in the face of adversity. This is a crucial aspect to consider when examining the coping of university students in critical situations such as COVID-19. OBJECTIVE: This study aims to assess the association between resilience and mental health outcomes among university students in Cyprus during the post-COVID-19 pandemic era. METHODS: A parallel embedded mixed methods research design will be utilized to assess resilience, measured by the Conner-Davidson Resilience Scale (CD-RISC), the COVID-19 Impact Scale (CIS) and mental health outcomes measured by the Symptom Checklist 90-Revised (SCL 90-R), during the COVID-19 post-pandemic era (January 2022-July 2024) among university students in the Republic of Cyprus. The study will be conducted in two stages: a pilot study followed by the main study. Quantitative data will be collected through a web-based survey, while qualitative data will be obtained through in-person focus groups designed to capture participants' experiences. Participants will be recruited using a proportional quota sampling approach to achieve representativeness based on predefined demographics. The study protocol has been approved by the Cyprus Bioethics Committee (approval no: EEC/EP/2023/31). DISCUSSION: This study is expected to broaden our understanding of the intricate interactions between the COVID-19 pandemic's impact, resilience, and mental health outcomes. The focus on university students' psychological wellbeing is consistent with the call by the WHO to focus on mental health (World Health Organization, 2019).

Nursing Student Knowledge Related to Sepsis in Croatian, Cypriot, and Greek Universities: A Cross-Sectional European Study.

BACKGROUND: Although the treatment of sepsis has advanced during the past 20 years there is still a high incidence and high mortality, which make sepsis one of the leading public health problems. Adequate knowledge of sepsis and the sepsis guidelines is still the most important pillar for nurses because of the long time they spend with critically ill patients. Given their frontline role in patient care, nurses are pivotal in early sepsis recognition, timely intervention, and ensuring adherence to treatment protocols. AIM: This study aimed to investigate nursing students' knowledge of sepsis and the symptoms of sepsis, and to compare the results of nursing students from several European universities (Croatia, Cyprus, Greece). METHODS: A cross-sectional design was used, with a sample of 626 undergraduate nursing students from Croatian, Cypriot, and Greek universities from 2022 to 2023. Demographic features (gender, age, employment, year of study) and a questionnaire provided by Eitze et al. were utilized as instruments. RESULTS: There was a statistically significant difference among the countries (F(2.625) = 4.254, p = 0.015) in average knowledge about sepsis, with Scheffe's post hoc test indicating that the Cypriot students had a higher average knowledge than the Greek students (p = 0.016), while students from neither country were significantly different from Croatian students (both p > 0.05). CONCLUSIONS: This study showed the still limited knowledge of nursing students and the differences among the educational programs for nursing students. The educational curricula of nursing studies should increase the number of sepsis lectures and use innovative techniques.

Adverse Childhood events of individuals and its relationship with resilience.

OBJECTIVE: The aim of this study is to examine the relationship between childhood trauma and psychological resilience in the Turkish Cypriot community and to identify the predictors of psychological resilience. METHOD: The research was conducted with 354 individuals in a web-based online environment in Northern Cyprus. Data were collected using a "Personal Information Form", the "Adverse Childhood Events Scale", and the "Resilience Scale for Adults". Percentage, mean, standard deviation, and Pearson's correlation analysis were used in the data analysis. RESULTS: In the study, 16.67 % of the participants were exposed to war or conflict when they were young and 10.17 % had a mental illness. In addition, it was determined that there were statistically significant and negative correlations between the Adverse Childhood Events Scale scores and the scores they got from the Adult Resilience Scale and the sub-dimensions of the scale. Female gender and education level predicted the scores on the Resilience Scale for Adults positively, and the presence of mental disease and the scores on the Adverse Childhood Events Scale negatively predicted the scores on the Resilience Scale for Adults. CONCLUSION: In this study, gender, educational status, presence of mental illness, and the total score on the Adverse Childhood Events Scale were determined to be predictive variables affecting resilience. Considering the research findings, it is recommended that nurses plan studies for the protection of the mental health of children and adolescents and the groups exposed to trauma should be psychologically supported to raise individuals with high resilience.

Gender-Based Variation in Alveolar Bone Thickness of Maxillary Incisor Teeth: A CBCT Retrospective Study.

BACKGROUND This retrospective study from a single center in Cyprus aimed to assess labial (buccal) and palatal bone thickness in 6 anterior maxillary teeth of 120 adults using cone-beam computed tomography (CBCT). MATERIAL AND METHODS The CBCT scans of 120 patients (720 teeth) were examined, with scanning parameters of 90 kvP, 24 s, 4 mA, voxel size 0.3 mm, and field of view of 10×6 cm. All maxillary incisors were categorized into 3 distinct points in terms of buccal (B) and palatal (P) points, with points B1 (buccal) and P1 (palatal) 4 mm below the cementoenamel junction; points B2 and P2 at the midpoint between the labial and palatal alveolar crest plane extending to the root apex; and points B3 and P3 at the root apex. Evaluation was done by measuring the distance from these points to the labial and palatal alveolar bone. RESULTS When the thicknesses were measured between all 6 points and labial and palatal bone, the thickness of point B3 of tooth 13 in men was significantly higher than that in women. At points P1, P2, and P3 for teeth 11 and 13, the palatal bone thickness of men was significantly higher than that of women. At points P2 and P3 of tooth 12, the palatal bone thickness of men was significantly higher than that of women. CONCLUSIONS The study found a correlation between alveolar bone thickness and patient sex in the North Cyprus population. Alveolar bone thickness in the anterior maxillary should be considered in implant treatment and orthodontic techniques.

The impact of IVF patients' characteristics on their satisfaction and quality-of-life with overseas treatment: A mixed methods approach.

Recent advances in infertility therapy, such as hormone medication and in vitro fertilization (IVF), have led to an increase in the demand for IVF. North Cyprus is a new medical tourist destination, and this study aimed to discover influential demographic predictors of IVF patients' satisfaction and quality-of-life (QoL) after receiving reproductive IVF services. Two questionnaires on IVF patient satisfaction and QoL were administered to 101 patients who received services in selected IVF clinics. Parametric and nonparametric tests were used for statistical analysis. The results showed that the mean satisfaction level with IVF service introduction and doctor professionalism increased with age, and a maximum satisfaction level was found in older patients. Doctor professionalism was another significant factor for greater satisfaction in older patients than in young patients who underwent IVF treatment. Satisfaction with IVF services was reduced by increasing education levels. IVF services must be managed and provided based on the needs of patients from different demographic backgrounds and efforts must be made to improve satisfaction with fertility services.

Modeling the HIV epidemic in MSM in Cyprus: reaching only the 95-95-95 cascade of care targets fails to reduce HIV incidence by 90% in 2030.

National responses should be improved and accelerated to meet the target of ending the Acquired ImmunoDeficiency Syndrome (AIDS) epidemic by 2030. In the Republic of Cyprus, Men who have Sex with Men (MSM) are disproportionately affected by Human Immunodeficiency Virus (HIV), accounting approximately for half of all annual HIV diagnoses. This study assesses the evolution of HIV incidence in MSM in Cyprus until 2030 using a model calibrated to Cypriot epidemiological data. Four scenarios were examined: status quo, two scenarios focusing on introducing Pre-Exposure Prophylaxis (PrEP), and a 90% HIV incidence reduction scenario. Reaching only the 95-95-95 HIV cascade of care targets among MSM would reduce HIV incidence by 48.6% by 2030 compared to 2015. Initiating a PrEP intervention only for high risk MSM would cause a modest further reduction in HIV incidence. To meet the 90% reduction target, PrEP should be expanded to both high and medium risk MSM and, after 2025, behavioral interventions should be implemented so as high-risk MSM gradually move to the medium-risk category. Cyprus will not reach the HIV incidence reduction target by 2030 unless PrEP is gradually promoted and delivered to all high and medium risk MSM along with awareness and behavioral interventions.

Temporal trends of cancer incidence rates for the most frequent cancer sites in Cyprus (2004-2017).

BACKGROUND: Cancer is one of the leading causes of morbidity and mortality, worldwide. Little information is available for the temporal trends of cancer in the Mediterranean region, including Cyprus. AIMS: We aimed to analyze cancer incidence trends overall and by sex for the period 2004-2017 regarding the five most common cancer sites for the population of Cyprus. METHODS AND RESULTS: Data were obtained from the nationwide cancer registry dataset that included 27 017 total cancer cases in Cyprus (2004-2017). We estimated the crude, sex-, and age-specific, as well as age-standardized (ASR) cancer incidence rates and we analyzed the time trends of ASR using the joinpoint regression program. For the general population (0-85+ years of age), the most common cancer sites in descending order, were breast, prostate, lung, colorectal, and thyroid cancer. During the study period, breast and thyroid cancer ASR presented a significant (p < .05) increasing temporal trend. Lung cancer ASRs seemed to stabilize (no increase or decrease) during the more recent years (2009 onwards) for both sexes; a similar pattern was observed for colorectal cancer in males. The ASRs of prostate cancer in men were in steady decline from 2012 onwards and the same was observed for the female ASRs of colorectal cancer from 2007 onwards. The colorectal cancer ASR temporal patterns overall, during the whole study period appeared unchanged. CONCLUSION: This temporal analysis would feed into cancer surveillance and control programs that focus on prevention, early detection, and treatment, particularly for cancer sites of higher mortality rates or those with temporally increasing trends.

Determination of Breast Cancer Risk and Knowledge Levels in Women: The Case of Cyprus.

BACKGROUND: Breast cancer is the type of cancer that is seen all over the world and ranks first among female cancers in terms of incidence and cause of death. OBJECTIVE: This research was conducted to determine the breast cancer risk level and breast cancer knowledge level in women living in Northern Cyprus. METHODS: The study, which was planned as a relational survey, was carried out as web-based. The research was completed with 657 adult female participants living in Northern Cyprus who volunteered to participate in the study. In order to collect data, the first section includes the introductory features, the second section includes the "Breast Cancer Risk Assessment Form" for determining breast cancer risk levels, the third section includes the "Comprehensive Breast Cancer Knowledge Test" to determine the breast cancer knowledge levels of the participants, and the fourth section includes the "Champion Health Belief Model Scale" was used. RESULTS: It was determined that 95.2% of women were in the low risk group for breast cancer. The knowledge test mean score is 12.05, and it can be said that the scores obtained are above the average (min:4- max:18). It was found that 55.7% of the women knew how to do Breast Self-Examination (BSE), but only 15.4% of them regularly performed BSE every month. It was found that 80.9% of the women never had mammography and their knowledge scores increased with increasing education level (p< 0.001) and there was a significant relationship between non-smokers and their knowledge levels (p< 0.01). IMPLICATIONS FOR PRACTICE: Despite the high scores of women in knowledge tests, it was observed that the frequency of applying BSE and having mammography was very low. Regardless of the risk factors for breast cancer, the importance of regular check-ups and BSE for every woman should be taught to women by health professionals, and group trainings should be planned for women who do not have training on this subject.

Temporal trends in temperature-related mortality and evidence for maladaptation to heat and cold in the Eastern Mediterranean region.

The eastern Mediterranean region is characterized by rising temperature trends exceeding the corresponding global averages and is considered a climate change hot-spot. Although previous studies have thoroughly investigated the impact of extreme heat and cold on human mortality and morbidity, both for the current and future climate change scenarios, the temporal trends in temperature-related mortality or the potential historical adaptation to heat and cold extremes has never been studied in this region. This study focuses on cardiovascular mortality and assesses the temporal evolution of the Minimum Mortality Temperature (MMT), as well as the disease-specific cold- and heat-attributable fraction of mortality in three typical eastern Mediterranean environments (Athens, Thessaloniki and Cyprus). Data on daily cardiovascular mortality (ICD-10 code: I00-I99) and meteorological parameters were available between 1999 and 2019 for Athens, 1999 to 2018 for Thessaloniki and 2004 to 2019 for Cyprus. Estimation of cardiovascular MMT and mortality fractions relied on time-series Poisson regressions with distributed lag nonlinear models (DLNM) controlling for seasonal and long-term trends, performed over a series of rolling sub-periods at each site. The results indicated that in Athens, the MMT decreased from 23 °C (67.5th percentile) in 1999-2007 to 21.8 °C (62nd percentile) in 2011-2019, while in Cyprus the MMT decreased from 26.3 °C (79th percentile) in 2004-2012 to 23.9 °C (66.5th percentile) in 2011-2019. In Thessaloniki, the decrease in MMT was rather negligible. In all regions under study, the fractions of mortality attributed to both cold and heat followed an upward trend throughout the years. In conclusion, the demonstrated increase in cold attributable fraction and the decreasing temporal trend of MMT across the examined sites are suggestive of maladaptation to extreme temperatures in regions with warm climate and highlight the need for relevant public health policies and interventions.

A revised radiocarbon calibration curve 350-250 BCE impacts high-precision dating of the Kyrenia Ship.

The Kyrenia Ship, found off the north coast of Cyprus, is a key vessel in the history of scientific underwater excavations and in the history of Greek shipbuilding. The first volume of the site's final publication appeared in 2023 and provides detailed archaeological information tightly constraining the dating of the ship. A very specific date range is proposed: ca. 294-290 BCE, but is based on a less than certain reading of one coin recovered from the ship. While there is clear benefit to finding high-precision dates for the Kyrenia Ship and its rich assemblage using independent scientific dating (combined with Bayesian chronological modeling), efforts to do so proved more challenging and complex than initially anticipated. Strikingly, extensive radiocarbon dating on both wooden materials from the ship and on short-lived contents from the final use of the ship fail to offer dates using the IntCal20 calibration curve-the current Northern Hemisphere radiocarbon calibration curve at the time of writing-that correspond with the archaeological constraints. The issue rests with a segment of IntCal20 ca. 350-250 BCE reliant on legacy pre-AMS radiocarbon data. We therefore measured new known-age tree-ring samples 350-250 BCE, and, integrating another series of new known-age tree-ring data, we obtained a redefined and more accurate calibration record for the period 433-250 BCE. These new data permit a satisfactory dating solution for the ship and may even indicate a date that is a (very) few years more recent than current estimations. These new data in addition confirm and only very slightly modify the dating recently published for the Mazotos ship, another Greek merchant ship from the southern coast of Cyprus. Our work further investigated whether ship wood samples impregnated with a common preservative, polyethylene glycol (PEG), can be cleaned successfully, including a known-age test.

Preferences and perceptions of 617 migraine patients on acute and preventive migraine treatment attributes and clinical trial endpoints.

BACKGROUND: To identify the preferences and perceptions of migraine patients for acute and preventive treatment options and to investigate which treatment outcomes are the most important. DESIGN AND METHODS: The authors performed a choice-format survey in a cohort of migraine patients from Greece and Cyprus. A self-administered questionnaire developed in collaboration with the Greek Society of Migraine Patients was used. RESULTS: Questionnaires were collected from 617 migraine patients. Efficacy was preferred over safety as the single most important parameter, both in acute and preventive treatment. When analyzing single outcomes, patients prioritized a complete pain remission at 1-hour post-dose for acute therapies. Regarding migraine prevention, a 75% reduction in frequency, intensity of pain, accompanying symptoms and acute medication intake were considered as most important. Conversely, outcomes routinely used in clinical trials, namely complete or partial pain remission at 2-hours post-dose for acute treatment and 50% or 30% reduction in migraine frequency for prevention, were not deemed particularly relevant. Tablet formulation was mostly preferred, both in acute and preventive treatment. Conclusion: Listening to patients' needs may add a piece of the puzzle that is generally missing in clinical practice and often explains the lack of adherence in both acute and preventative anti-migraine therapies.

Morphological Variations of the Nasopalatine Canal in the North Cyprus Population: A Cone Beam Computed Tomography Study.

BACKGROUND This study aimed to evaluate the morphological characteristics of the anterior maxillary nasopalatine canal and the width of the buccal bone using cone-beam computed tomography (CBCT) in 150 adults in Northern Cyprus. MATERIAL AND METHODS The study included 150 participants, and their anterior maxillary morphometric measurements (eg, length of the nasopalatine canal and anteroposterior diameter of the nasal foramen) were taken using CBCT with the scanning parameters of 90 kvP, 24 s, 4 mA, voxel size 0.3 mm, and field of view 10×6 cm. The shapes of the nasopalatine canal (NPC) were categorized into 4 types: cylindrical, hourglass, funnel-shaped, and banana (54%, 20.6%, 18.6%, and 4%, respectively). RESULTS The findings showed a clear link between the shape of the NPC and the horizontal dimensions of the anterior maxilla's morphometric properties. In general, decreased horizontal bone dimensions were found in the premaxilla at the banana- and funnel-shaped type for the nasopalatine canal. Also, the anteroposterior diameter of a nasal foramen in the hourglass shape was significantly larger in diameter than all other shapes. Additionally, the morphology of the nasopalatine canal is influenced by its shape. The sagittal cross-section has shown significant correlations with the sizes of the incisive foramen, nasal foramen, and the length of the nasopalatine canal. CONCLUSIONS The study found a correlation between the shape of the NPC and the horizontal dimensions of the anterior maxilla's anatomy. The measurements of NPC in a North Cyprus population slightly differ from the established standards found in the existing literature. Conducting more extensive studies with a larger number of CBCT images will offer additional insights.

A cross-sectional study of university students' awareness, knowledge, and attitudes on organ donation and transplantation in Northern Cyprus.

BACKGROUND: Understanding the knowledge and attitudes of university students regarding organ transplantation and donation is crucial, as these students can significantly influence public opinion and behavior. This study aims to assess the knowledge and attitudes of North Cyprus University students towards organ transplantation and donation. METHODS: A cross-sectional study was conducted with 400 students from Northern Cyprus University, divided into medical and social science faculties. A structured questionnaire was utilized to assess their knowledge and attitudes towards organ transplantation and donation. Descriptive statistics, Chi-square tests, and effect size calculations were employed for data analysis. RESULTS: Among the 400 students, 27% demonstrated sufficient knowledge of organ transplantation, and 62.7% had positive views on organ donation. Willingness to donate was expressed by 37% as living donors and 64% as deceased donors. There were no significant differences in knowledge and attitudes between medical and social science students. Factors such as sex, marital status, faculty, and contact with individuals with end-stage organ failure did not significantly influence the knowledge and attitudes. CONCLUSIONS: This study highlights the necessity for educational interventions and awareness campaigns to improve understanding and attitudes towards organ donation among Northern Cyprus University students. Incorporating organ donation education into university curricula, providing accurate online information, addressing misconceptions, and promoting awareness of donation centers and transplant hospitals are essential steps to mitigate organ shortages. Public engagement should be encouraged to foster a supportive environment for organ donation.
